A composition for removing coats of paint or varnish from any surface should contain an energetic softening or loosening agent, and should remove the paint thus softened from the surface without injury to the latter. It should also leave the surface thoroughly cleaned. Another essential requirement is that it should not generate poisonous or obnoxious gases and should not injure the hands of the person applying same.

It is well known to the art that aints are made of quite a variety of compositions. It

is therefore evident that, in order to be effective, a paint remover should attack paints of various compositions. My preparation will satisfy the above requirements, as an analysis of the several ingredients will show. For example, Sal-soda when used alone will attack some paints but is not effective on a good many others, particularly hard varnish or very old paint. Alcohol will readily attack the spirit varnishes, but is of little effect on other varieties of paints. Benzol will gelatinize most of the paints but will not remove them from the surface. Benzol and alcohol if used without the other ingredients are found to be objectionable on account of the fumes generated and the large quantity Specification of Letters Patent.

of alcohol required to carry away the dissolved paint." By adding sal-soda and paraflin to the last two mentioned ingredients,

.a composition is obtained which will not generate fumes and will readily remove all kinds of paints from any surface in a very short tlme. Due to the combined action of the benzol and alcohol, the paint is softened and left in a gelatini zed state, while the salsoda separates the gelatinized paint from the surface, forming a paste which can be readily washed off with water. The function of theparaflin is to prevent the evaporation of the alcohol and benzol and to serve as a lubricant.

' Instead of'paraiiin any other wax composition may be used giving satisfactory results. I find, however, that paraliin will give good results and is less expensive than other wax compounds.

It will be found that by combining the various ingredients in the proportion men- I tioned above a very effective composition to be used as a paint remover Willbe obtained. This preparation will remove paint irrespective of its age, hardness or quality.

A very important feature of my composition is that water ma be used to wash away the dissolved paint rom the surface of the object being cleaned, thus re uiring only a small quantity of the preparation for softening the aint. Another advantage of this composition is that no poisonous or obnoxious gases are produced and it will not injure the hands of a person using same.

The process of preparing this composition is as follows:

A quantity of parafiin or other wax compound is melted and then mixed with heated alcohol in the proportion of 8% to 14% (by volume), to this, and while in molten state, a hot, concentrated solution of sal-soda containing 30% of Sal-soda and 20% of water -(by volume) is added, to this 28% (by volis Well dissolved the surface should be washed off with water.

Having thus described my invention, 1 claim as new and wish to secure by Letters Patent 1. The herein-described composition of matter to be used as a paint remover, consisting of any wax compound, alcohol, water, Sal-soda and benzol.

I 2. The herein-described composition of matter to be used as a paint remover, conslsting of parafiin, alcohol, water, sol-soda and benzol.

3. The herein-described composition of matter to be used as a 'paint remover, con- 15 sisting of parafii-n 8% alcohol li /1, water 20%, sal-soda 3072; and benzol 28%.
